Precautions

Your doctor will check your progress after you receive this medicine. This will allow your doctor to see if the medicine is working properly and to check for unwanted effects.

Tell your doctor right away if you have any change in your heart rhythm. The symptoms may include feeling dizzy or faint, or having a fast, pounding, or uneven heartbeat. Make sure your doctor knows if you or anyone in your family has ever had a heart rhythm problem such as QT prolongation.

Check with your doctor right away if you have difficulty breathing, a fast heartbeat, a high fever, a change in blood pressure, increased sweating, loss of bladder control, severe muscle stiffness, unusually pale skin, or tiredness. These could be symptoms of a serious condition called neuroleptic malignant syndrome (NMS).

Droperidol will add to the effects of alcohol and other central nervous system (CNS) depressants (medicines that make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for hay fever, allergies, or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; barbiturates or other seizure medicines; and muscle relaxants. Check with your doctor before taking any of these medicines after you receive droperidol.
